T0 @ZZ whom it may con/cern:

Be it known that I, EDUARD TCHLER, blacksmith, of 56 Staudgasse, Vienna,in the Empire of Austria-Hungary, have invented Improvements Relating toHorseshoes and to Calks Therefor, of which the following is a full,clear, and exact description.

This invention relates to horseshoes and to calks therefor, and moreparticularly to the connection of the calk or grip to the horseshoe,which differs from other existing constructions in the manner in whichthe calk or grip is securely mounted in position and can nevertheless bedetached with very little trouble. f

AnotherI feature of my invention is to provide a horseshoe on the treadthereof with a number of teeth, ribs, or .sharp projections for thepurpose of preventing the horse from slipping.

To facilitate comprehension, I have illustrated my said invention in theaccompanying drawings, in which- Figure lis a front view of a horseshoe.Fig. 2 is a section on line x @0,Fig. 1. Fig. 3 is a section on line yy, Fig. 4. Fig. 4 illustrates a plan view of the horseshoe, showingpartly the upper side and partly the under side of the horseshoe. Fig. 5shows a calk or grip in a section on line 2 e, Fig. 7. Fig. 6 is a frontelevation of the calk. Fig. 7 is a plan view of Fig. 5. Fig. 8illustrates a section of the .horseshoe connected with the calk. Fig.' 9is a plan view thereof. Figs. 10 and Il show a calk with balls ofindia-rubber inserted therein. Figs. 12 and 13 are sections takenrespectively on lines u u and c o of Fig. 4.

The easily-detachable connection of the calk or grip to the horseshoe iseffected by providing the said calk with one or more pins or projectionswhich are introduced into suitable holes or sockets in the horseshoe,where they are secured by keys or wedges. The horseshoe may also beprovided with ribs, teeth-cones, prisms, or the like, tapering towardtheir extremities. By this arrangement the dirt from the street will becompressed into the interstitial spaces between the ribs, the. The sharpedges, however, cut through the dirt and enable the horse to obtain aiirm foothold on asphalted streets, and by reason of the plurality ofpoints of contact the danger of slipping is reduced to a minimum.

In carrying my said invention into practice I preferably proceed asfollows: The horseshoe 1 is provided with two transverse holes orapertures 2 and 3, extending through the entire height of the shoe,these holes being preferably of halfround form. On the under side thehorseshoe is provided with a projecting plate 4, which is made of I formin order to leave the said transverse holes or apertures free. On thefront-of the horseshoe there is anl aperture 5, which extends throughthe whole width of the bar for a purv pose to be hereinafter mentioned.The calk G, which corresponds in form to the said plate V4, is providedwith a depression or recess 7,

and with two pins or projections 8 9, which are made with lateral slots,so as to form hooks, and iit into the said transverse holes or apertures2 and 3. In order `to connect the calk to the horseshoe, the said pins 8and 9 are inserted from beneath into the said transverse apertures 2 and3, Figs. 8 and 9, and are drawn up by means of a key or wedge 10, whichis inserted into the front aperture 5 and is provided with a head orfiange 11 at the rear. The said key bears on one side against the saidplate 4, and on the other side engages with the hooks of the calk, andthus insures the latter being'securely held in position.

The pins 8 and V9 can be arranged horizonn tally on the calk or grip, inwhich case the holes or apertures 2 3 in the horseshoe are.

also horizontal-that is to say, they must extend in the direction of thebreadth of the bar. In this case the key or wedge ispreferablyflrstinserted behind the horseshoe into one or both pinswithout passing through the same.

The calk or grip itself can either be sharpedged or Iiat. It can also bemade in the form of a prism, open at the bottom, the edges of which arecut away, so that the side walls 13 extend straight downward and form aspace for the reception of india-rubber balls 12, Figs. 10 and l1. Inthis manner it is IOO vent slipping of the horse. In order to hold theindia-rubber fast, the side Walls are preferably bent inward after theindia-rubber is placed in position.

The tread of the horseshoe may be provided with ribs, teeth, prisms, orthe like, tapering toward their extremities, which is to be seen on theupper half of Fig. et and the sections thereof in Figs. 12 and 13. Thisarrangement makes the horseshoes comparatively light, and they do notfatigue the horses as do the shoes at present in use. Moreover, thehorses are protected from shock, and inammation of the hoof is entirelyavoided.

Having thus described the nature and object of my invention, what Iclaim as new, and desire to secure by Letters Patent, is

Thejcombination with a horseshoe provided with two apertures extendingvertically through the shoe and an aperture extending horizontallythrough the same, a plate of substantially I form located on the underside of the horseshoe adjacent to the vertical and horizontal apertures,a removable calk or grip provided with pins or projections ofsubstantially hook shape adapted to enter the vertical apertures in theshoe, and a key or wedge adapted to enter the horizontal aperture of theshoe and to rest between the hooks of the calli-pins and the I-plate ofthe shoe, substantially as and for the purposes described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
